To all'whomz'tmey concern:

Be it known that L-Loms A. Simxorna citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful'Improvements in Spring Cushion Constructions, of which the following is a specification.

This invention relates to improvements in spring cushion constructions adapted for incorporation in seat and mattress structures, and the present application is a division of my former application which has issued as Letters Patent of the United States .No. 1,397,021, dated November 15, 1921.

The objectof the present invention is to provide a construction 'of this character wherein maximum economy may be effected in the amount of materials employed when producing the same.

Furthermore, the invention also contemplates the provision of a novel form and arrangement of the spring units and their envelopes, whereby but a slngle ply of material is present between contiguous springs, thus eliminating unnecessary use of the fabric of the envelopes and at the same time providing the requisite separation of the springs to prevent their contact with each other. The sound of the springs in their relative movement with respect to each other is thereby precluded,while material saving in the textile fabric of the envelopes or covering for the springs is effected.

Other objects and advantages will a pear as the nature of the improvements is tter understood, the invention consisting substantially in the novel construction, combination and arrangement of parts hereinafter fully described, illustrated in -the accompanying drawings. and finally pointed out in the appended claims.

In the drawings- Fig. 1 is a top plan view of the hereindescribed invention, the springs being illustrated in dotted lines.

Fig. 2 is a detail vertical transverse sectional view on the line 2-2, Fig. 1.

Fig. 3 is a similar view on the line 3-3, Fig. 1. p

Fig. 4 is a fragmentary perspective view, parts being broken away, of the herein described cushion construction, the springs beingomitted.

eferrin now in detail to the accompany ing drawings, it will be observed that the herein described s ring cushion construction includes a plurality of individual springs bottom la er 11, which layers preferably are formed 0 textile fabric, and said layers constitute the top and bottom or face portions of the cushion construction. Obviously, the dimensions of these 1a ers are such as are required to be include in the finished product. Arranged between the top and bottom layers 10 and 11,. and extending across one dimension thereof, is a series of continuous division walls or partitions 12, which partitions are parallel to each other and spaced apart the required distance, and their upper and lower edges are connected, as at' 13 to the layers 10 and 11. This is effected preferably by stitching, but other equivalentfastenin'gs may be employed. Arranged at right angles to the continuous partitions 12 is a plurality of division walls or partitions 14, each of-which is formed ofan unbroken web of material. These are only sufliciently wide to extend between the continuous walls .or partitions 12, and their upper and lower ends 15 are connected permanently to the top and bottom layers 10 and 11, respectively, as by stitchlng 16 or its equivalent. These walls or partitions 14 are spaced from each other a sufiicient distance to provide the desired size of spacing or pocket, and

in each of these pockets is positioned a coil spring 17 From the foregoing description it will be observed that there is but a single ply of finished cushion. The upper and lower edges of the continuous partitions 12 and of the short division walls or partitions 14 only are connected to said top and bottom. This leaves the edges of the division walls or partitions 14 w olly disconnected from the contiguous continuous walls 12, the free edges of the division walls 14 and the continuous walls 12 cooperating to form openin s at the corners of the pockets, thus enab ing ready access to be had to the several pockets for introduction and removal of the respective springs to and from these pockets. The ends of the springs bear against the top 10 and bottom 11 and reuire no connection therewith, the expansive force of the springs distendi the fabric of the cushion structure, an thereby lacing the walls 12 and 14 under tension. The sprin thus are freely displaceable, and as no istenings are required for holding the springs in place they may be uickly introduced to and positioned within t eir respective pockets when assembling the cushion construction.

A significant feature of the hereindescribed structure is the fact that but a single ply of material is required to separate the several springs from each other, and this economizes in the amount of material em loyed in formin the division walls.

ft will be observe further that the openings at the corners of the pockets are aligned in the direction of the continuous walls 12, thus permittinglthe springs of all the pockets between eac pair of continuous walls to be introduced simultaneously thereto for positioning therein, as by the use of the inserting tool made the subject of Letters Patent No. 1,352,157 granted to me Septemher 7, 1920. These ogenings enable such tool readily to be. gui ed and passed into the pockets for discharge thereinto from the tool of the several springs carried thereby. This efiects filling of the springs into the several pockets in a most rapid and eflicient manner.

I claim:

1. A spring cushion construction of the class described, comprising a top, a bottom spaced therefrom, a. plurality of continuous spaced partitions arranged between said top and bottom and connected thereto at their upper and lower edges, a plurality of division walls arranged in the spaces between said continuous partitions and extending at right angles to the! latter to divide said spaces into a plurality of pockets, each of said division walls being formed of an unbroken. web the ends of which are connected rmanently to said top and bottom and tli: side edges of which are free,

pockets, the free edges of said division walls and the continuous partitions co-operating to form openings through which said springs may be guided and passed into said pockets when positioning the springs in the latter.

2. A spring cushion construction of the 7 class described, comprising op sitely disposed layers constituting the ace portions of the cushion and spaced apart a predetermined distance to accommodate therebetween the resilient elements of the cushion, a series of continuous parallel s aced partitions arranged between said ayers and extending across one dimension thereof, said partitions being connected along their opposite edges to said la ers, a plurality of division walls arrange across the spaces between said continuous partitions and dividing the latter into a series of pockets each of which receives one of the resilient elements of the cushion, each of said divi sion walls being formed of an unbroken web connected permanently along its ends to said op ositely disposed layers, and a pluralit o springs arranged in said pockets, sai division walls being freeat their edges from connection with the continuous partitions and co-operating with the latter to form openings through which said springs may be guided and passed into said ockets when positioning the springs in the atter, said openin s bein located at the corners of the poo ets an ali ed in the direction of the continuous wa s, whereb the springs of all the pockets between eac pair of continuous walls may be introduced simultaneously thereto for positioning therein.

In testimony whereof I have hereunto signed my name in the presence of two subscribing witnesses.
